Example in usage message for HalideTraceViz uses nonexistent flags (`-s` and `-t` in lieu of `--size` and `--timestamp`)

[parkerziegler]

Description

A very minor issue I came across while playing around with HalideTraceViz. The top example in the usage message on L296 uses the -s and -t flags in lieu of --size and --timestamp. Running this on a local pipeline results in the following message:

Argument parsing failed at argument 1

<Usage message>

Just opening an issue with the goal of fixing the error message!

Reproducing case

Using any Halide pipeline, run the following (JIT mode):


HL_TARGET=host-trace_all HL_TRACE_FILE=/dev/stdout <command to make and run pipeline> | \
HalideTraceViz -s 768 1280 -t 10000 \
ffmpeg -f rawvideo -pix_fmt bgr32 -s 768x1280 -i /dev/stdin -c:v h264 output.mp4
